The honest take
Technical SEO, under the hood.
Technical SEO isn't glamorous, but it decides whether Google can even crawl, render and trust your site. Get it wrong and great content stays invisible.
What it is
Everything under the hood.
Everything under the hood that decides whether Google can crawl, render and trust your site: speed, Core Web Vitals, crawlability, indexing, structured data and a clean site architecture.
When it's the right tool
Good content that won't rank.
When your content is solid but not ranking, when you've migrated or replatformed, or when the site has grown messy over the years. Usually the first thing worth fixing.
When it isn't
Already technically healthy.
If your site is already technically healthy, another audit won't move the needle. The win then is content and authority, not another crawl. Honest answer.
How Aesthetic runs it.
- Audit and crawlA full crawl and Core Web Vitals check to find what's blocking, slowing or confusing Google.
- Fix the foundationsSpeed, indexing, redirects and crawl issues sorted, so every page can be found and served fast.
- Structure and schemaClean architecture, internal linking and structured data, so Google and AI can read exactly what each page is about.
Why it matters
The work nobody sees, behind every ranking.
Technical SEO rarely gets the credit, because when it's done right nothing looks different. Things just start ranking. Ignore it and here's what it quietly costs you.
Content that never ranks
Great pages stay invisible because Google can't crawl or render them properly.
Slow, clunky pages
Poor Core Web Vitals drag every ranking down and push visitors away before they convert.
Wasted crawl budget
Duplicate URLs, broken redirects and crawl traps burn the attention Google gives your site.
Unreadable to AI
No structured data, so you miss rich results and AI Overviews can't quote you.
The honest case
It's the groundwork every other tactic quietly depends on. Fix it once and your content, links and local work all start pulling harder, for the same effort.
What is technical SEO?
Technical SEO is the under-the-hood work that lets search engines crawl, render, understand and trust your site: speed, Core Web Vitals, indexing, structured data and site architecture.
What's a technical SEO audit?
A full review of your site's health: a crawl, a Core Web Vitals check, indexing and redirect analysis, and a prioritised list of what's holding rankings back and what to fix first.
What are Core Web Vitals?
Google's measures of real-world page experience: loading speed, responsiveness and visual stability. Poor Core Web Vitals scores can hold rankings back and frustrate visitors.
Why isn't my content ranking even though it's good?
Often it's technical. If pages are slow, blocked, duplicated or hard to crawl, Google can't reward the content. Fixing the foundations is usually what unlocks it.
What is crawl budget?
It's how much of your site Google will crawl in a given window. Waste it on duplicate or broken URLs and your important pages get crawled less often.
What is schema, and do I need it?
Schema, or structured data, is code that tells search engines what your content means. It powers rich results and helps AI Overviews quote you accurately. Most sites benefit.
Will technical SEO fix a traffic drop after a redesign or migration?
Usually, yes. Migrations commonly break redirects, URLs and indexing. A technical audit finds what was lost and recovers it.
How often do I need a technical audit?
A thorough one once or twice a year for most sites, with lighter checks after any big change to the site or platform.
Do you fix the issues or just hand me a report?
Both. You get the audit and the fixes implemented, not a PDF of problems left for you to solve.
How long does technical SEO take to show results?
Some fixes, like speed or indexing, can show within weeks. Structural and crawl improvements compound over the following months.
What platforms do you work on?
WordPress, Shopify, Webflow and most common builds. The principles are the same; the implementation is tailored to your platform.
How do you measure technical SEO?
Crawlability and indexing, Core Web Vitals scores, pages indexed, and the rankings and traffic that follow, all in plain-English reporting.
